The problem is you can't view reviews like "How much should I buy this game, on a scale from 1-10?" It should be read as a persons take on the game. You should cross reference different reviews to get something little less bias. Then you need to consider that some game reviewers like Harvest Moon, TES:Oblivion, and other titles you may not like.
The Captain America game got bashed scoring in around a 6 I think. I think the game is fun. I went in wanting a comic-bookey game and that is what I got, I was pleased. I think for what it was trying to do, it deserves an 8-9. It wasn't trying to be anything more than the fun super hero games I grew up playing borrowing some mechanics from Arkham Asylum. That is what I found out from all the reviews and developer releases and that is what I wanted from it.
Personally, I find game reviewers pretty accurate. I don't care about the numbers or the "this is why this sucks" lines. All I need to know is the facts. Reading a review, I am always trying to take out the bias lines.
This is what should be done. Reviewers are gamers like me and you, though they get paid to do these reviews. Subjective standpoints are inevitable and unavoidable. They are just people with likes and dislikes similar, and dissimilar, to your own.
Reviews offer a SINGLE perspective on a game. It is not a definitive rating. Accepting one review as objective facts about a game is a bogus use of them. Even when rating seemingly objective aspects to a game like graphical fidelity, gameplay mechanics and audio, there are a plethora of subjective nuances that will sway the reviewers opinion. For example, Aesthetically pleasing vistas for one reviewer may trump shoddy textures while for another the textures might be unbearable despite the overall effect OR where one person lambastes the Classic Resident evil for it's sluggish and brutal control scheme but laud Resident Evil 4 for it's refinement of the interactivity in the game, another Reviewer may see that improvement as crippling to the Survival Horror aspects in the series, where the classic tank controls added tension and "almost nightmare like" quality to the horror.
Bias in any medium is expected. But it shouldn't be damnable. You don't (or shouldn't) chastise a friend for liking/loving a game you found boring/abhorrent, likewise you shouldn't slam all reviewers who don't share an opinion to your own. There ARE bad reviewers for sure, usually they are amateurs who completely avoid critical thinking and instead see themselves as Critics, without a proper understanding of what a "critic" is in reviews. But these reviewers are the same as you... again, they shouldn't be flamed for an opinion.
Of course tossing my two cents into this. The internet is so full of blowhards and egotists, that expecting humble and rational approaches to anything with an opinion is liable to get me flamed too.
The key to efficient utilisation of Reviews is, as Savagezion said, to cross reference multiple reviews. Even if you trust your go to reviewer, alternative perspectives will only enrich your knowledge of what makes good gaming and make you more tolerant to the vastly opinionated interwebs.
Finally, a good way to gauge the Objecitve quality of a game is to use mass review sites like Metacritic and other of the same vein. But be careful of User reviews, they are good for alternative and "unprofessional" takes on games (films/music etc) which add perspective, but they aren't held accountable for blasting a game that competes with their favourite game (see whichever side of the BF3 and MW3 debate) or for adding cynical and jaded remarks that are heavily weighted in the negative, but not always based on the qualities of the actual product.(not to mention they are generally worse at putting a score to their reviews, usually landing on extremes with little beyond a "IT'S THE SHIT" or "IT'S SHIT" remarks in place of a review.
EDIT: Also, look up youtube vids that demonstrate the actual game (outside of official demos). I find that a good way to gauge whether a game is worth the dosh or if I need to let the price drop again (or ignore it altogether).
